Airbed

ABSTRACT

An airbed is provided with an inflation and deflation valve, which includes a base fixedly disposed at an inflation and deflation port and a sealing plug detachably disposed on the base. The airbed has an electric air pump is part of the sealing plug and is integrated with the sealing plug. A housing of the electric air pump is used as part of the inflation and deflation valve of the airbed and serves as the sealing plug of the inflation and deflation valve. When the airbed needs to be deflated, the electric air pump is directly removed, and then air is rapidly exhausted through a large diameter exhaust port. The airbed can be produced in advance without being limited by the specification of the electric air pump, and afterwards, the electric air pump is screwed or buckled on the airbed in a sealed manner.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to CN 201710816096.2 filed 2017 Sep. 12, which is incorporated herein by reference.

TECHNICAL FIELD

The invention relates to an airbed provided with a detachable electric pump.

DESCRIPTION OF RELATED ART

In the prior art, internal pumps need to be welded to airbeds at a high frequency in the prior art, and consequentially, the airbeds are limited by the specification of the air pumps and cannot be produced in advance. With the need for hot melting of the air pumps welded to the airbeds at a high frequency, the air pumps need to be coated for a second time. Once quality problems happen to the air pumps hot melted to the airbeds, it is extremely difficult to repair the air pumps, resulting in a high manufacturing cost and a high after cost.

BRIEF SUMMARY OF THE INVENTION

The objective of the embodiments of the invention is to overcome the above-mentioned defects of the prior art by providing an airbed, which can be rapidly deflated and be produced in advance without the need of secondary coating and can also reduce the after cost and manufacturing cost.

In these embodiments, an airbed of the invention is provided with an inflation and deflation valve, which includes a base fixedly disposed at an inflation and deflation port and a sealing plug detachably disposed on the base. The innovation of the airbed of the invention lies in that an electric air pump serves as part of the sealing plug and is integrated with the sealing plug.

In one embodiment of the invention, the electric air pump in the airbed is a one-way spiral internal pump, which is connected to the base in a threaded manner.

In one embodiment of the invention, the electric air pump in the airbed is a two-way spiral internal pump, which is connected to the base in a threaded manner.

In one embodiment of the invention, the electric air pump in the airbed is a buckle internal pump, which is connected to the base in a buckled manner.

Compared with the prior art, the housing of the electric air pump is used as part of the inflation and deflation valve of the airbed and serves as the sealing plug of the inflation and deflation valve; when the airbed needs to be deflated, the electric air pump is directly removed, and then air is rapidly exhausted through a large-diameter exhaust port. In addition, the airbed can be produced in advance without being limited by the specification of the electric air pump, and afterwards, the electric air pump is screwed or buckled on the airbed in a sealed manner. After being detached from the airbed, the electric air pump can serve as a common electric air pump to be applied to other inflatable products. Once the electric air pump has certain quality problems, better after-sales services can be provided, and thus, the after cost and manufacturing cost of products are reduced.

DETAILED DESCRIPTION OF THE INVENTION

The invention is further illustrated in combination with the drawings and specific embodiments as follows. It would appreciate that these embodiments are only used to explain the invention instead of being used to limit the protection scope of the invention. After reading the contents recorded in this specification, those skilled in this field can make various alterations or modifications to the preset invention, and all these equivalent alterations and modifications should also fall within the scope defined by the Claims of the invention.

In the following embodiments of the invention, the pump structures of a one-way spiral internal pump, a two-way spiral internal pump and a buckle internal pump basically have no difference and can be any pump structures with an inflation function in this field.

As shown in FIGS. 1 and 2, an airbed in a first preferred embodiment of the invention is provided with an inflation and deflation valve, which includes a base fixedly disposed at an inflation and deflation port and a sealing plug detachably disposed on the base. As shown in FIG. 10, an electric air pump is part of the sealing plug and is integrated with the sealing plug. In this embodiment, the electric air pump is a one-way spiral internal pump, which is connected to the base in a threaded manner. As shown in FIG. 9, in order to avoid air leakage, sealing rings are disposed at a joint (primary seal in FIG. 9) of an electric air pump housing (part of the sealing plug) and the base as well as an external joint (part of the electric air pump, secondary seal in FIG. 9).

As shown in FIG. 3 and FIG. 4, an airbed in a second preferred embodiment of the invention is provided with an inflation and deflation valve, which includes a base fixedly disposed at an inflation and deflation port and a sealing plug detachably disposed on the base. As shown in FIG. 10, an electric air pump is part of the sealing plug and is integrated with the sealing plug. In this embodiment, the electric air pump is a two-way spiral internal pump, which is connected to the base in a threaded manner. As shown in FIG. 9, in order to avoid air leakage, sealing rings are disposed at a joint (primary seal in FIG. 9) of an electric air pump housing (part of the sealing plug) and the base as well as an external joint (part of the electric air pump, secondary seal in FIG. 9).

As shown in FIG. 5-8, an airbed in a third preferred embodiment of the invention is provided with an inflation and deflation valve, which includes a base fixedly disposed at an inflation and deflation port and a sealing plug detachably disposed on the base.
